## Description

The Adafruit DS1841 is an I2C-controlled logarithmic digital potentiometer from Maxim with a resistance range of 3.7 kΩ to 22 kΩ across 128 tap points. Unlike linear potentiometers, the DS1841's logarithmic response curve makes it particularly well suited for audio applications such as volume control, where it better matches the human ear's perception of sound levels. The DS1841 also features built-in temperature compensation with hysteresis, plus a 72-entry look-up table (LUT) that maps specific wiper positions to temperature ranges from -39°C to 100°C. The breakout includes STEMMA QT / Qwiic connectors for solderless I2C wiring and works with 3.3V or 5V logic. Key Features Logarithmic Response – Ideal for audio volume control and human-perception-matched applications 128 Tap Points – Fine resolution across 3.7 kΩ to 22 kΩ range Temperature Compensation – Built-in automatic resistance adjustment based on temperature 72-Entry Look-Up Table – Map wiper positions to specific temperature ranges I2C Control – Simple digital interface with STEMMA QT / Qwiic connectors 3.3V and 5V Compatible – Works with a wide range of microcontrollers Ideal For Audio volume control circuits Temperature-compensated analogue adjustments Digitally controlled calibration Replacing mechanical potentiometers with software control Package Contents 1× DS1841 I2C logarithmic potentiometer breakout with STEMMA QT connectors Note: STEMMA QT cable not included. Compatible with CircuitPython and Arduino libraries.
